Best Known (55, 55+111, s)-Nets in Base 4

(55, 55+111, 66)-Net over F₄ — Constructive and digital

Digital (55, 166, 66)-net over F₄, using

t-expansion [i] based on digital (49, 166, 66)-net over F₄, using
- net from sequence [i] based on digital (49, 65)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 49 and N(F) ≥ 66, using
    - T₆ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(55, 55+111, 91)-Net over F₄ — Digital

Digital (55, 166, 91)-net over F₄, using

t-expansion [i] based on digital (50, 166, 91)-net over F₄, using
- net from sequence [i] based on digital (50, 90)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 50 and N(F) ≥ 91, using
    - a curve from the manYPoints database [i]

(55, 55+111, 411)-Net in Base 4 — Upper bound on s

There is no (55, 166, 412)-net in base 4, because

1 times m-reduction [i] would yield (55, 165, 412)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2317 507287 474717 824137 468667 390335 252311 126230 568259 091089 981547 991334 792435 685801 113829 298765 724120 > 4¹⁶⁵ [i]
